These cycle times may be of interest.
They were taken 30 minutes after I switched on the machine. Ambient temperature 22°C
Machine: Grimac Eclisse commercial 2-group with 10-litre boiler
Pressurestat contactors close: 0.65 Bar. For 21 seconds, supplying 2300 watts to the heating element.
Pressurestat contactors open: 0.85 Bar. For 1 minute 50 seconds during which no electricity flows to the heating element.
Water temperature at shower screen: 93°C
For 11 years this bullet-proof machine has worked away without a problem. No parts have been replaced.
I did clean the contacts on the touchpads which can corrode and make them a little sticky. https://coffeesnobs.com.au/brewing-e...tml#post535152
A few months ago I dissassembled the contactors on the Sirai pressurestat, and removed the build up of carbon deposits.
Perhaps surprisingly, the diaphragm of the pressurestat was still very supple and working well, so the Sirai continues in its original state giving solid reliable service with a deadband of 0.2 Bar.
